Stripe, an online payment processing platform used by the likes of Rackspace, Shopify, Reddit, Foursquare and Lyft, has released a new version of its Checkout widget that includes a completely redesigned mobile checkout experience.

"We've learned a lot about what works and what doesn't over the past year, and we've redesigned Checkout from scratch for every device," the company writes in its blog about the updates. "Checkout is gorgeous on Android, iOS, Windows Phone, [Macintosh] OS X, Windows, tablet, desktop and mobile."

Stripe has more than $130 million of venture backing. Some of the investors behind the company include Sequoia Capital, Andreessen Horowitz, Khosla Ventures, Founders Founder, Allen & Co.; and PayPal co-founders Peter Thiel, Max Levchin, and Elon Musk.

The Checkout service, launched about one year ago, is focused on developers, content creators and Internet companies that need to process transactions online. It is used to process "billions of dollars" of commerce for thousands of companies, according to Stripe. Aside from the mobile enhancements already mentioned, two other new features include:

Support for separate biling and payment addresses, as well as integrated billing address verification

A "remember me" checkbox that allows customers to save payment information, by associating the record with their mobile phone number
